I told one of my friends about the Stanford OCW and he found the "Lectures on Fourier Transforms for Electrical Engineers". http://www.youtube.com/watch?v=gZNm7L96pfY&feature=PlayList&p=B24BC7956EE040CD&index=0 Since it is summer time, he said he might spend time looking through that stuff. The question is if it will be useful for him or not as he wants to be a physicist and is currently doing a BSc in Physics. So what do you think? Will learning about the Fourier Transform how Electrical Engineers learn it help somewhere along the line? Is it any different from how physicists would learn about it?
